Is there a benchmark showing that the multi delete performs multi key

None that I know about ;). But you may experiment with mdelete.t in
the server, or 05_delete_multi.t in the Perl module.
I have no doubts it will outperform single deletes because of the
latency of waiting the reply before sending the next command. More
interesting would be to compare it to streamed delete, like the one
that Marc is willing to share, but not yet.
It's not that hard to add multi-delete to the current clients with the
existing protocol. You can just pipeline the commands, sending all the
deletes, then reading all the responses. It means there is "\r\ndelete "
between each key instead of just " ". It may be slightly more cpu
intensive, but compared to the network latency saved, the extra cpu time
will be utterly insignificant.
